I have a 302 that is damn near new off of a rebuild.
Its bored .60 over, large cam, headers, 4 barrel 650cfm Edlebrock, performer rpm mid rise intake and a high flow oil pump.

I have been having problems here recently with smoke out of the drivers side pipe, but when the engine gets warm, it moves to both pipes.
I have done a compression test and each cylinder is reading at about 135psi.
I am starting to have what I think is a little bit of valve noise.
Oil is reading right where it should be, but its burning it from somewhere.

Any ideas or suggestions of things to try?
I am almost at my wits end.
Thanks in advance.

 

Oil can get past the rings....not likely in a good rebuilt.
It can also get by the intake valve seals....best bet.
It can come in through the crankcase ventilation system....a fair bet.
